A sheriff's lieutenant says Williams' personal assistant found the actor yesterday in a bedroom at Williams' home.

According to Sheriff's Lt. Keith Boyd, Williams had been seeking treatment for depression. Boyd isn't saying whether Williams left a suicide note.

The actor's wife had last seen him the night before, and had left the home that morning thinking he was still asleep. Williams' personal assistant later came to the home and became concerned when he knocked on the door and got no response.

It will take weeks to get the results of toxicology tests on whether Williams had any drugs or alcohol in his system.

Fans and friends have been leaving bouquets, candles and personal notes in front of the locked gates of the home. Neighbors say he had lived in the quiet, waterfront neighborhood for eight years, and that he was friendly and approachable.

If someone you know exhibits warning signs of suicide:

Do not leave the person alone

Remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt

Call the U.S. National Suicide Prevention Lifeline at 800-273-TALK(8255)

Take the person to an emergency room or seek help from a medical or mental health professional
